Re: [Qemu-discuss] Modern Network Interface Card emulation

[Wink Saville]

Here is the output and indicates the most upto date chipset is the "q35" apparently from 2009, I guess better than the alternative i440Fx from 1996:

Good advice, thank you. As far as what the PC base chip set is, good question, I'll see if I can find out.

Yea, I saw that, but I couldn't find any motherboards with an 8254x chip (maybe that's the wrong chip), would you happen to of know of one?

Qemu can emulate an Intel e1000, which while a bit old is still being
built into systems.

If it is still being built into systems, it is probably as
part of a larger chip/chipset such as a "northbridge", where
it shares the silicon with stuff like the SATA controllers
and the USB2/3 host controller.

I have not specific ideas as to which Ethernet programming
interface is in which of the modern chipsets.  One of the
best ways to find out would probably be to look in the
e1000 driver files in Linux, those usually contain a list
of PCI IDs of compatible adapters, which you can then
lookup online to see the names of the chipsets (if not
already mentioned in that list).

On a similar note, I wonder if the "PC" model in qemu is
still stuck emulating a now historic base chipset that
originally didn't support PCIe.

Enjoy
